The main drag of this place must be the location, and that it's well-priced especially if you're a group of people (my room would easily sleep four people). BTS Phloen Chit is a few metres away.
The place is actually a hotel, so rooms go to different sides and not all have a view toward the skyline. Looks like they all have balconies though.
Despite the location near a highway and the BTS, I never heard any noise (with my balcony going to the back of the building, away from BTS). The building staff is friendly, access is 24/7.
The rooms aren't exactly new but in decent enough shape with everything working fine. Amenities are rather basic, but you can ask if you need anything more - like, extra cutlery or glasses or towels or such.
The deposit for utilities is a bit of an inconvenience because it makes your actual cost a bit of a black box, unless you already have an idea how much these things cost in Bangkok. To give you an idea, my total was about 1500 Baht in a month (though I was away for 10 days, so that's really rather 20 days). Likewise, cleaning needs to be paid extra (200 Baht), which is fine as it allows for an undisturbed stay and can be requested for example when you're away.
